WebDec 27, 2016 · This type of flow pattern is sometimes referred to a tardus parvus waveform, which, loosely translated, means “slow to rise, slow to fall.” FIGURE 8-8. Doppler sample taken further downstream from the stenosis shows a delayed systolic upstroke and a delayed systolic deceleration phase. WebBoth vertebral arteries will then exhibit a parvus tardus waveform (Fig. 9A, 9B, 9C, 9D). If both vertebral arteries and carotid arteries and their branches reveal parvus tardus waveforms or a delayed systolic upstroke, the cause is more likely a high-grade stenosis at the aortic valve.
